The D-Link DWL650 is one of the cheaper Prism2Cards available.

Updated!
Jouni Malinen has included a workaround for this goofball card and its Vcc issues. Should work in a real PCMCIA slot with the prism2 driver and this switch (from his driver changelog):
- added new module parameter 'ignore_cis_vcc' to ignore broken Vcc configuration some wireless LAN cards (mainly D-Link)
From Fall 2001:
It is a PCMCIA card, but won't configure unless its (I've seen so far) in a cardbus slot. My guess is that it's PCMCIA but requires 3.3V, and the PCMCIA stuff I have available will only do 5V.
At any rate, to get this puppy working in an older Toshiba (tried on Tecra 720CDT and 740CDT) requires the BIOS option of Cardbus/16-bit instead of PCIC-compatible, and you'll only find support for the ToPIC95 and later chips in the newer external pcmcia-cs packages-- not the kernel tree. I don't know why they don't keep the kernel code in sync but they seem to be very different indeed.
The same is true under Windows too -- the BIOS must be changed to Cardbus and you'll have to install the proper Cardbus drivers. Otherwise, the card is detected, and you can install drivers, but it just sits there. Like it didn't configure.
I thought I'd pass this bit of knowledge along in case there's any more Toshiba owners out there.
The jist of this is now I've got 3 Prism2Cards in 3 Linux systems and I can sniff the full conversation. There is some debugging to be done with the driver in client mode methinks... sometimes I can't reassociate, etc.
